Watched the video clip of the '53 Muntz-excellent restore job and the set works well with the Zenith convertor.The Muntz CAN do well with a good signal and restore job.As I said we can say the simplicity of these sets in this case could be a salvation for them-fewer parts to replace in restoring them.The audio on that '53 set sounded really nice!!Those Tvs are are in attractive cabinets-sure does beat plastic!But note all of that space under the big,deep chassis!Sooo-the old Muntz may be worth consideration for restore and use with a convertor box.Haven't found a ONE of those in my area--Best Buy used to have them.
